The Cairo-dock icons are my own, shoot be a PM if you want them and I'll upload them somewhere.

I only heard of Neptune when 4.10 RC3 was released, Neptune seem to be one of the distro that had the 4.10 betas available. It has a few bugs (can't seem to add new services in dolphin, I miss the dropbox services) but I think it is more on the KDE side rather than the distro itself. It is very similar to LMDE-KDE.

Orbmiser, that looks cool so far. I have had terrific luck with KDE, hope you have the same kind of luck. KDE just seemed real easy to theme to me and it has ran rock solid on my laptop and desktop. Keep up the nice work!
